Jenkins Features Controlled with System Properties

Whether to use the minified (false) or debug (true) JS files for the YUI library.

This is the path to jenkins.war and set by executable.Main when invoked using java -jar jenkins.war. This allows Jenkins to find its own .war file and e.g. replace it to apply an update. If undefined, Jenkins will not e.g. offer to update itself.

Specify a location for additional bundled plugins during plugin development (hpi:run). There is no reason this would be set by an administrator.

Disable the bytecode transformer that retains compatibility at runtime after changing public Java APIs. Has no effect since 2.296, as the bytecode transformer has been removed.

Unused between 1.527 and 2.309. Since 2.310, can be set to false to use URLClassLoader instead. This is the default since 2.347.

Client-side HTTP CLI ping interval in milliseconds. Set on the CLI client (java -jar jenkins-cli.jar), not Jenkins server process.

Whether to load unsigned console notes. See SECURITY-382 on Jenkins Security Advisory 2017-02-01.

How many KB of console log to show in default console view. This property had no effect from Jenkins 2.4 (inclusive) until 2.98/2.89.3 (exclusive), see JENKINS-48593.

If there’s less than this amount of free disk space, in bytes, on the disk with the Jenkins home directory, and the disk is 90% or more full, a warning will be shown to administrators.

Set to true if the servlet container doesn’t support chunked encoding.

Set to true to disable DNS multicast. Has no effect since 2.220 as the feature has been removed. See SECURITY-1641

Max. number of operations to validate a file mask (e.g. pattern to archive artifacts).

Allows tweaking the URL displayed at the bottom of Jenkins' UI

Number of seconds between reloads when Auto Refresh is enabled. Obsolete since the feature was removed in Jenkins 2.223.

Jenkins 2.205 and newer attempts to prevent browsers from offering to autofill password form fields by using a custom password control. Setting this to false reverts to the legacy behavior of using mostly standard password form fields.

Specify full class name for Lifecycle implementation to override default. See documentation for class names.

Disable security hardening for LogRecorderManager Stapler access. Possibly unsafe, see 2018-12-05 security advisory.

This is set to true by the development tooling to identify when Jenkins is running via jetty:run or hpi:run. Can be used to distinguish between development and production use; most prominently used to bypass the setup wizard when running with an empty Jenkins home directory during development.

When using jenkins-core.jar from the CLI, this is the connection timeout connecting to Jenkins to report a build result.

Controls whether URLs implementing markup formatter previews are accessible via GET. See 2021-01-13 security advisory.

Controls whether to set restrictive Content-Security-Policy headers on URLs implementing markup formatter previews. See 2021-01-13 security advisory.

Use shorter but cryptic names in matrix build workspace directories. Avoids problems with 256-character limit on paths in Cygwin, path depths problems on Windows, and shell metacharacter problems with label expressions on most platforms. See JENKINS-25783.

Disable security hardening related to Stapler routing for AbstractItem. Possibly unsafe, see 2018-12-05 security advisory.

Set to true to permit accessing the Jenkins remote API in an unsafe manner. See SECURITY-47. Deprecated, use e.g. Secure Requester Whitelist instead.

The number of minutes after which to try and rotate the log file used by any AsyncAperiodicWork extension. For fine-grained control of a specific extension you can use the FullyQualifiedClassName.logRotateMinutes system property to only affect a specific extension. It is not anticipated that you will ever need to change these defaults.

When starting a new run of any AsyncAperiodicWork extension, if this value is non-negative and the existing log file is larger than the specified number of bytes then the log file will be rotated. For fine-grained control of a specific extension you can use the FullyQualifiedClassName.logRotateSize system property to only affect a specific extension. It is not anticipated that you will ever need to change these defaults.

Interval between periodic downloads of Downloadables, typically tool installer metadata.

Suppress the periodic download of data files for plugins via browser-based download. Since Jenkins 2.200, this has no effect.

Skip the update site signature check. Setting this to true can be unsafe.

Matrix parent job and other flyweight tasks (e.g. Build Flow plugin) won’t consume an executor when true. Unused since 1.598, flyweight support is now always enabled.

Deprecated: Backward-compatible fallback for jenkins.model.Jenkins.initLogLevel. Removed since 2.272.

Deprecated: Backward-compatible fallback for jenkins.model.Jenkins.killAfterLoad. Removed since 2.272.

Load statistics clock cycle in milliseconds.

Decay ratio for every clock cycle in node utilization charts.

Font used for load statistics. See Java documentation on how the value is decoded.

Whether to allow building flyweight tasks even if the necessary permission (Computer/Build) is missing. See JENKINS-46652.

If true, not discard parameters for builds that are not defined on the job. Enabling this can be unsafe. Since Jenkins 2.40, if set to false, will not log a warning message that parameters were defined but ignored.

Comma-separated list of additional build parameter names that should not be discarded even when not defined on the job.

Defines the refresh period for the internal queue cache (in milliseconds). The greater period workarounds web UI delays on large installations, which may be caused by locking of the build queue by build executors. Downside: Builds appear in the queue with a noticeable delay.

Maximal delay of a save operation when content of Jenkins queue changes. This works as a balancing factor between queue consistency guarantee in case of Jenkins crash (short delay) and decreasing IO activity based on Jenkins load (long delay).

More artifacts than this will use tree view or simple link rather than listing out artifacts

More artifacts than this will show a simple link to directory browser rather than showing artifacts in tree view

When true, don’t automatically check for new versions

Read timeout in seconds for downloading plugins.

Disable security hardening related to Stapler routing for UpdateCenter. Possibly unsafe, see 2018-12-05 security advisory.

Deprecated: Override the default update site URL. May have no effect since Jenkins 1.333.

Set to true to opt out of usage statistics collection, independent of UI option.

When true, does not check auth realm for existence of user if there’s a record in Jenkins. Unsafe, but may be used on some instances for service accounts

Whether admins accessing /user/example creates a user record (see SECURITY-406 on Jenkins Security Advisory 2017-02-01)

When false, skips part of the fix that tries to determine whether a given user ID exists, and if so, doesn’t consider users with the same full name during resolution.

Disable security hardening related to Stapler routing for User. Possibly unsafe, see 2018-12-05 security advisory.

Control an agent based on a schedule

When set to true, Jenkins will guess the repository browser used to render links in the changelog.

When set to true, Jenkins will not reference resource files through the /static/…​/ URL space, preventing their caching. This is set to true during development by default, and false otherwise.

Limits the number of results a search can render.

Disable security hardening related to Stapler routing for Search. Possibly unsafe, see 2018-12-05 security advisory.

If set to true, restore pre-2.46 behavior of sending HTTP headers on "access denied" pages listing group memberships.

The Artifacts permission allows to control access to artifacts; When this property is unset or set to false, access to artifacts is not controlled

Escape hatch for SECURITY-1774.

Escape hatch for SECURITY-626.

Restore the ability to disable CSRF protection after the UI for doing so was removed from Jenkins 2.222.

Escape hatch for SECURITY-868

The WipeOut permission allows to control access to the "Wipe Out Workspace" action, which is normally available as soon as the Build permission is granted

Frequency (in minutes) of pings between the controller and agents. Deprecated since 2.37, use hudson.slaves.ChannelPinger.pingIntervalSeconds instead.

Frequency of https://wiki.jenkins.io/display/JENKINS/Ping+Thread[pings between the controller and agents], in seconds

Timeout for each https://wiki.jenkins.io/display/JENKINS/Ping+Thread[ping between the controller and agents], in seconds

Whether to enable this feature that checks whether agents are alive and cuts them off if not.

How frequently to check for channel activity, in milliseconds.

How long to wait after startup to start checking agent connections, in milliseconds.

How long to wait after startup before starting to provision nodes from clouds. This will allow static agents to start and handle the load first.

How frequently to possibly provision nodes.

Allow connection by agents running unsupported remoting versions.

When concurrent builds is enabled, a unique workspace directory name is required for each concurrent build. To create this name, this token is placed between project name and a unique ID, e.g. "my-project@123".

When true, builds don’t fail when there is nothing to archive

When true, jobs associated through fingerprints are added to the dependency graph, even when there is no configured upstream/downstream relationship between them.

Number of lines of console output to include in emails

Host name that Jenkins advertises to inbound TCP agents. Especially useful when running Jenkins behind a reverse proxy.

Port that Jenkins advertises to inbound TCP agents. Especially useful when running Jenkins behind a reverse proxy.

Enables the experimental nested views feature. Has no effect since 2.302, as the experimental nested views feature has been removed.

Allows to move the logs usually found under $JENKINS_HOME/logs to another location. Beware that no migration is handled if you change it on an existing instance.

Milliseconds waiting for polling executor before trigger reports it is clogged.

Port for UDP multicast broadcast. Set to -1 to disable. Has no effect since 2.220 as the feature has been removed. See SECURITY-1641

Pass blame information to downstream jobs.

Disables the forced flushing when calling //close(). Not expected to be used.

Set to true to disable the filter that sets request encoding to UTF-8 if it’s undefined and its content type is text/xml or application/xml (API submissions).

Set to true to force the request encoding to UTF-8 even if a different character set is declared.

The time (in milliseconds) to wait between attempts to delete files when retrying. This has no effect unless hudson.Util.maxFileDeletionRetries is greater than 1. If zero, there will be no delay between attempts. If negative, the delay will be a (linearly) increasing multiple of this value between attempts.

Opts out of a change in default behavior that disables the processing of XML external entities (XXE) for the Digester2 class in Jenkins if set to true. This system property can be changed while Jenkins is running and the change is effective immediately. See 2.263.2 upgrade guide. Has no effect since 2.297, as the Digester2 class has been removed.

Controls whether to set restrictive Content-Security-Policy headers on URLs implementing form validation responses. This reduces the impact of cross-site scripting (XSS) vulnerabilities in form validation output. See 2.263.2 upgrade guide.

Controls the maximum size (area) for requests to render graphs like load statistics. See 2021-01-13 security advisory.

The number of times to attempt to delete files/directory trees before giving up and throwing an exception. Specifying a value less than 1 is invalid and will be treated as if a value of 1 (i.e. one attempt, no retries) was specified. See JENKINS-10113 and JENKINS-15331.

Limits the number of form fields that can be processed in one multipart/form-data request. Used to set org.apache.commons.fileupload.servlet.ServletFileUpload//setFileCountMax(long). Despite the name, this applies to all form fields, not just actual file attachments. -1 disables this limit.

Limits the size (in bytes) of individual fields that can be processed in one multipart/form-data request. Despite the name, this applies to all form fields, not just actual file attachments. -1 disables this limit.

Limits the total request size (in bytes) that can be processed in one multipart/form-data request. Used to set org.apache.commons.fileupload.servlet.ServletFileUpload//setSizeMax(long). -1 disables this limit.

True to disable creation of symbolic links in job/builds directories

If this flag is set to true then we will request a garbage collection after a deletion failure before we next retry the deletion. It is ignored unless hudson.Util.maxFileDeletionRetries is greater than 1. Setting this flag to true may resolve some problems on Windows, and also for directory trees residing on an NFS share, but it can have a negative impact on performance and may have no effect at all (GC behavior is JVM-specific). Warning: This should only ever be used if you find that your builds are failing because Jenkins is unable to delete files, that this failure is because Jenkins itself has those files locked "open", and even then it should only be used on agents with relatively few executors (because the garbage collection can impact the performance of all job executors on that agent). Setting this flag is an act of last resort - it is not recommended, and should not be used on your main Jenkins server unless you can tolerate the performance impact.

True to disable cleanup of child processes.

Number of log entries in loggers available on the UI at /log/

If set to true, Old Data Monitor will record some failures to load data submitted by users with Overall/Administer permission, partially disabling a security fix. See 2021-01-13 security advisory and hudson.util.RobustReflectionConverter.recordFailuresForAllAuthentications.

If set to true, Old Data Monitor will record some failures to load data submitted by all authorized users, completely disabling a security fix. See 2021-01-13 security advisory and hudson.util.RobustReflectionConverter.recordFailuresForAdmins.

Jenkins automatically round-trips f:password based form fields as encrypted Secret even if the field is not of type Secret. Set this to false to disable this behavior, doing so is discouraged.

If the user is missing Item/Configure permission, Jenkins 2.236 and newer will blank out the password value automatically even if the form field is not backed by a Secret. Set this to false to disable this behavior, doing so is discouraged.

Force a particular crypto provider; with Glassfish Enterprise set value to SunJCE to workaround JENKINS-6459 and GLASSFISH-11862.

Jenkins no longer automatically flushes streams for code running remotely on agents for better performance. This may lead to loss of messages for plugins which print to a build log from the agent machine but do not flush their output. Use this flag to restore the previous behavior for freestyle builds.

True to use exec of "ln" binary to create symbolic links instead of native code

True to use native (JNA/JNR) implementation to set file permissions instead of NIO. Removed without replacement in 2.304.

The maximum number of seconds that adding elements to collections may cumulatively take when loading an XML document using XStream, or -1 to disable. See 2022-02-09 security advisory for context.

Set to false to not force session tracking to be done via cookie. Escape hatch for JENKINS-61738.

How many builds to show in the build history side panel widget.

Defines a limit for the characters shown in the description field for each build row in the Build History column. A positive integer (e.g. 300) will define the limit. After the limit is reached (…​) will be shown. The value -1 disables the limit and allows unlimited characters in the build description. The value 0 shows no description.

Backward compatible fallback name for JENKINS_HOME. See documentation there.

true to disable Jenkins CLI via JNLP and HTTP (SSHD can still be enabled). This has no effect since 2.165.

During the start of Jenkins, the loading of jobs in parallel have a fixed number of threads by default (twice the CPU). To make Jenkins load time 8x faster (assuming sufficient IO), increase it to 8x. For example, 24 CPU Jenkins controller host use this: -Djenkins.InitReactorRunner.concurrency=192

Set to false to skip install wizard. Note that doing so leaves Jenkins unsecured. Development-mode only: Set to true to not skip showing the setup wizard during Jenkins development. This property is only effective the first time you run Jenkins in given JENKINS_HOME.

This property determines the behavior during the SetupWizard install phase concerning the API Token creation for the initial admin account. The behavior depends on the provided value:

A token is generated using random value at startup and the information is put in the file $JENKINS_HOME/secrets/initialAdminApiToken.

A fixed API Token will be created for the user with provided value as the token.

A fixed API Token will be created for the user with the value read from the file. Jenkins will not delete the file after read, so the script is responsible to remove it when no longer needed.

A comma-separated list of additional top level path segments that should be accessible to users without Overall/Read permission. See 2021-01-13 security advisory.

The configuration of a given job is located under $JENKINS_HOME/jobs/[JOB_NAME]/config.xml and its builds are under $JENKINS_HOME/jobs/[JOB_NAME]/builds by default. This option allows you to store builds elsewhere, which can be useful with finer-grained backup policies, or to store the build data on a faster disk such as an SSD. The following placeholders are supported for this value:

true to enable crumb proxy compatibility when running the Setup Wizard for the first time.

true to disable throwing an IllegalStateException when Jenkins.getInstance() returns null

true to enable throwing an IllegalStateException when Jenkins.getInstance() returns null

When using the -Dhudson.lifecycle=hudson.lifecycle.ExitLifecycle, exit using this exit code when Jenkins is restarted

Log level for verbose messages from the init reactor listener.

Exit Jenkins right after loading. Intended as a development/testing aid only.

Log startup timing info. Note that some messages are not logged on levels visible by default (i.e. INFO and up).

Set to false to allow names to end with a trailing . character, which can cause problems on Windows. Escape hatch for SECURITY-2424.

Loads job configurations in parallel on startup.

Specifies the default TCP agent port unless/until configured differently on the UI. -1 to disable, 0 for random port, other values for fixed port.

If true, enforces the specified jenkins.model.Jenkins.slaveAgentPort on startup and will not allow changing it through the UI

Obsolete: Was used as the default workspace directory name in the legacy workspace directory layout (workspace directories within job directories).

Allows to change the directory layout for the job workspaces on the controller node. See jenkins.model.Jenkins.buildsDir for supported placeholders.

Disable URL validation intended to prevent an XSS vulnerability. See SECURITY-1471 for details.

Configure the kind of reference Jenkins uses to hold builds in memory. Choose from among soft, weak, strong, and not (do not hold builds in memory at all). Intended mostly as a debugging aid. See JENKINS-19400.

Whether to enforce new name restrictions for agent names. See 2021-01-13 security advisory.

true to disable GZIP compression of artifacts when they’re transferred from agent nodes to controller.  Uses less CPU at the cost of increased network traffic. ===== name: jenkins.monitor.JavaVersionRecommendationAdminMonitor.disable

true to disable the monitor that recommends newer Java versions.

true to allow users with Overall/Administer permission to create API tokens using the new system for any user. Note that the user will not be able to use that token since it’s only displayed to the creator, once.

True to show API tokens for users to administrators on the user configuration page. This was set to false as part of SECURITY-200

Do not perform any JEP-200 class filtering when deserializing data. Setting this to true is unsafe. See documentation.

Do not perform whitelist-based JEP-200 class filtering when deserializing data. With this flag set, only explicitly blacklisted types will be rejected. Setting this to true is unsafe. See documentation.

If Jenkins and plugins systems should prefer FIPS-140 compliant cryptography. Not all features/plugins have been adapted, and this only indicates a preference. If you set this flag to true, it does not make Jenkins and its plugins FIPS-140 compliant. Refer to Jenkins and FIPS-140 Overview for more information.

Whether to send X-Frame-Options: sameorigin header, set to false to disable and make Jenkins embeddable

When set to true, disable Basic authentication with username and password (rather than API token).

Enable the optional Overall/Manage permission that allows limited access to administrative features suitable for a hosted Jenkins environment. See JEP-223.

How long a resource URL served from the resource root URL will be valid for before users are required to reauthenticate to access it. See inline documentation in Jenkins for details.

This flag can be set to true to disable the agent-to-controller security system entirely. Since Jenkins 2.326, this is the only way to do that, as the UI option has been removed.

This flag can be set to false to explicitly reject Callable implementations that do not declare any required role. It is unclear whether this can safely be set to false in Jenkins before 2.335, or whether that would cause problems with some remoting built-in callables. This flag was removed in Jenkins 2.335.

Allow all file paths on the Jenkins controller to be accessed from agents. This disables a big part of SECURITY-144 protections.

Set to false to not reject attempts to access file paths in build directories of builds not currently being built on the accessing agent. Instead, only a warning is logged. Attempts to access file paths in build directories from other processes will still fail. See the description of the SECURITY-2458 security fix for context.

Set to true to disable the additional protection to not reject attempts to access file paths in build directories. This will restore access to any build directories both from agents and from other processes with a remoting channel, like Maven Integration Plugin. See the description of the SECURITY-2458 security fix for context.

Disables user seed. Escape hatch for SECURITY-901.

Hide the UI for user seed introduced for SECURITY-901.

Escape hatch for SECURITY-534.

Override the location of the user configurable whitelist for stapler view dispatches. This augments the built-in whitelist for SECURITY-534 that allows dispatches to views that would otherwise be prohibited.

Override the location of the user configurable whitelist for stapler request routing. This augments the built-in whitelist for SECURITY-595 that allows routing requests through methods that would otherwise be prohibited.

Prohibits access to public static fields when routing requests in Stapler. Escape hatch for SECURITY-595.

Skip (return) type check when determining whether a method or field should be routable with Stapler (i.e. allow any return type). Escape hatch for SECURITY-595.

Escape hatch for SECURITY-1774. Allows requests to URLs with semicolon characters (;) in the request path.

Enable the optional Overall/SystemRead permission that allows read-only access to administrative features suitable for a managed Jenkins Configuration as Code environment. See JEP-224.

How long a cache for UserDetails should be valid for before it is looked up again from the security realm. See JENKINS-35493.

false to disable the JNLP3 agent protocol, true to enable it. Otherwise, it’s randomly enabled/disabled to A/B test it. Obsolete since the protocol was removed in 2.214.

true to disable Nio for JNLP agents

Some Unix-like agents (e.g. SSH Build Agents) can communicate via stdin/stdout, which is very convenient. Unfortunately, some JVM output (e.g. related to GC) also goes to standard out. This will swap output streams around to prevent stream corruption through unexpected writes to standard out.

Set to false to not redact error messages when the agent-to-controller file path filters reject a file access. This can give attackers information about files and directories on the Jenkins controller file system.

Change the endpoint that JEP-214/Uplink telemetry sends data to. Expected to be used for testing only.

true to enable the new experimental UX on Jenkins. See JENKINS-60920. Also see Jenkins UX SIG. Has no effect since 2.344 as the feature has been removed.

Number of seconds a WebSocket agent connection may stay idle until it expires. 0 to disable. Must be higher than jenkins.websocket.pingInterval.

Number of seconds between server-sent pings over WebSocket agent connections. 0 to disable. Must be lower than jenkins.websocket.idleTimeout.

Debug/development option to slow down the cancelling of progressive rendering when the client fails to send a heartbeat.

While typically set as an environment variable, Jenkins also looks up the path to its home directory as a system property. JENKINS_HOME set via JNDI context has higher priority than this, but this takes precedence over the environment variable.

Allows to configure the SSHD client idle timeout (value in milliseconds). Default value is 10min (600000ms).

How long to wait, in seconds, before interrupting remote calls and forcing cleanup when the step is stopped. See JENKINS-46507 for more information.

true to enable the experimental push mode for durable task logging. See JENKINS-52165 for more information.

How long to wait, in milliseconds, before aborting the build if an agent has been removed. See JENKINS-36013 for more information.

false to prevent Jenkins from aborting the build if an agent has been removed. See JENKINS-49707 for more information.

Allows specifying non-simple names for views, including ones resulting in path traversal. This is an escape hatch for the SECURITY-867 fix.

Do not log attempts to set the class property of st:include tags directly. No log messages should be emitted in regular use, but they can be disabled if they cause unnecessary noise in the system log.

HTTP verbs of requests that are allowed to provide StaplerRequest//getSubmittedForm or @SubmittedForm. Escape hatch for a security hardening, see 2.277.2 upgrade guide.

Limits the number of form fields that can be processed in one multipart/form-data request. Used to set org.apache.commons.fileupload.servlet.ServletFileUpload//setFileCountMax(long). Despite the name, this applies to all form fields, not just actual file attachments. -1 disables this limit.

Limits the size (in bytes) of individual fields that can be processed in one multipart/form-data request. Despite the name, this applies to all form fields, not just actual file attachments. -1 disables this limit.

Limits the total request size (in bytes) that can be processed in one multipart/form-data request. Used to set org.apache.commons.fileupload.servlet.ServletFileUpload//setSizeMax(long). -1 disables this limit.

Controls both caching of various cacheable resources (Jelly scripts etc.) and the Expires HTTP response header for some static resources. Useful during development to see the effect of changes after reload.

Enables tracing of Jelly view composition. View the resulting page source to see comments indicating which parts of the view were created from which view fragments.

Do not filter get methods at the Stapler framework level. Escape hatch for SECURITY-595.

Do not filter web methods ("do" actions) at the Stapler framework level. Escape hatch for SECURITY-595.

Additional debug resource paths. Set by the core development tooling so developers can see the effect of changes immediately after reloading the page.

Trace request handling and report the result using Stapler-Trace-…​ response headers. Additionally, renders a diagnostic HTTP 404 error page when the request could not be processed.

Trace request handling (see above) for requests with the X-Stapler-Trace request header set.

Set the root directory used to load groovy hooks scripts.

When Multibranch Pipeline is reloaded from XML, it notifies its branch sources about it and triggers a scan if possible. This flag allows turning off this behavior. When Job DSL manages the items, this can avoid triggering many scans, which can potentially cause a build storm. The downside is that the branch source might use this notification to register webhooks or do any other useful setup work. ---
